• Rigid material behavior with moderate stiffness
• Designed for microfluidic (“MF”) applications and microchannel fabrication
• Clear, non-yellowing optical appearance
• Very high resolution with no light bleeding
• Precision down to ~5 µm (SLA/DLP/LCD) and up to ~100 nm (3D lithography)
• Chemically inert and hydrophobic (ULWA grade)
• Very low water absorption
• VOC-free formulation suitable for vacuum environments
• Low extractables and leachables for reduced cross-contamination risk
• Biocompatible-grade formulation
• Low tendency to gel beyond specification limits
• Durable with low shrinkage
• Organo-tin free formulation

Processing and handling performance

• Compatible with SLA, DLP, LCD and advanced 3D lithography systems
• Ultra low viscosity facilitates cleaning of ultra-fine microchannels
• Suitable for high-resolution exposure strategies with controlled curing depth
• Recommended for use in controlled laboratory environments
• Supports fabrication of complex internal geometries with high fidelity
• Strong adhesion to build platforms: use sufficiently long supports for safe removal
• Avoid direct printing on the build platform without supports to prevent breakage

Testing & processing disclaimer

Material performance depends on printer type, exposure conditions, geometry, cleaning protocols and post-processing. Microfluidic functionality, chemical compatibility and biological performance must be validated by the user for each specific application.
